Briefly analyzed the liquid chemical filling process flow and filling principle, application of material balance, gas state equation and process technology data, through the differential equation method and dynamic compensation method to establish the dynamic simulation mathematical model of filling process. Based on the simulation model of intelligent process control (IPC) and the application of automatic control configuration software Century Star, the method of dynamic simulation of the process was studied. The overall structure, overall technical scheme and principle of the simulation system were determined. User interface, the completion of the simulation process flow chart, all kinds of simulation command buttons and their display, as well as various components of the process and its parameters to adjust the simulation operation screen design and command language programming, with Visual C (VC ++) development The model calculation software, generated DLL, library functions, integrated with the graphical user interface, developed a complete set of dynamic simulation system to achieve a full dynamic simulation of the filling process. In the end, the principle simulation experiment of filling process was systematically carried out, the satisfactory simulation result was obtained and the process operating conditions of filling process were optimized.
